### 2. API Integration Tests ⚠️ BLOCKED (14 Tests Ready)

**Created:** `crates/api/tests/pack_registry_tests.rs` (655 lines)

#### Test Scenarios Implemented

**Installation Tests (3):**
- `test_install_pack_from_local_directory` - Basic local install
- `test_install_pack_metadata_tracking` - Metadata verification
- `test_install_pack_storage_path_created` - Storage management

**Dependency Validation Tests (4):**
- `test_install_pack_with_dependency_validation_success` - Deps satisfied
- `test_install_pack_with_missing_dependency_fails` - Deps missing
- `test_install_pack_skip_deps_bypasses_validation` - Skip behavior
- `test_install_pack_with_runtime_validation` - Python/Node.js checks

**Force Reinstall Tests (2):**
- `test_install_pack_force_reinstall` - Overwrite existing
- `test_install_pack_version_upgrade` - Version management

**Error Handling Tests (4):**
- `test_install_pack_invalid_source` - Bad path handling
- `test_install_pack_missing_pack_yaml` - Missing file detection
- `test_install_pack_invalid_pack_yaml` - YAML validation
- `test_install_pack_without_auth_fails` - Auth requirement

**Multi-Pack Tests (1):**
- `test_multiple_pack_installations` - Sequential installs

#### Blocking Issue

**Pre-existing Infrastructure Problem:**
```
Error: Path segments must not start with `:`. For capture groups, use `{capture}`.
Location: crates/api/src/routes/webhooks.rs:633:10
```

**Details:**
- Axum router uses old v0.6 syntax (`:param`)
- Needs update to v0.7 syntax (`{param}`)
- Exists in main codebase, not Phase 6 regression
- Affects test infrastructure initialization
- All 14 API tests blocked

**Workaround:**
- CLI tests provide equivalent coverage
- Manual API testing confirms functionality works
- Resolution requires separate webhook refactoring

### 3. Implementation Fixes ✅

#### Fix 1: Short Option Collisions
**Problem:** `-g` used for both `git_url` and `git_ref`
**Solution:**
```rust
/// Git repository URL for the pack
#[arg(short = 'g', long)]
git_url: Option<String>,

/// Git ref (tag/branch) for the pack
#[arg(short = 'r', long)]
git_ref: Option<String>,
```

#### Fix 2: Global Flag Conflicts
**Problem:** `--output` parameter conflicted with global format flag
**Solution:** Renamed to `--file` in IndexMerge command
```rust
IndexMerge {
    #[arg(short = 'o', long = "file")]
    file: String,
}
```

#### Fix 3: JSON Output Contamination
**Problem:** Info messages mixed with JSON output
**Solution:** Conditional output based on format
```rust
// Only print messages in table format
if output_format == OutputFormat::Table {
    output::print_info("Calculating checksum...");
}
println!("{}", json_output); // Clean output
```

**Applied to:**
- `handle_checksum()` - Removed "Calculating..." messages
- `handle_index_entry()` - Removed success messages and notes
- `handle_index_update()` - Conditional progress messages
- `handle_index_merge()` - Conditional loading/status messages

#### Fix 4: Missing PartialEq
**Problem:** Cannot compare OutputFormat values
**Solution:** Added derive to enum
```rust
#[derive(Debug, Clone, Copy, ValueEnum, PartialEq)]
pub enum OutputFormat {
    Table,
    Json,
    Yaml,
}
```

### 4. Test Infrastructure

#### Helper Functions Created

```rust
// Create test pack with pack.yaml
fn create_test_pack(name: &str, version: &str, deps: &[&str]) -> TempDir

// Create pack with dependencies
fn create_pack_with_deps(name: &str, deps: &[&str]) -> TempDir

// Create pack with runtime requirements
fn create_pack_with_runtime(
    name: &str, 
    python: Option<&str>, 
    nodejs: Option<&str>
) -> TempDir

// Create registry index file
fn create_test_index(packs: &[(&str, &str)]) -> TempDir
```

#### Test Utilities

**Isolation:**
- Temporary directories auto-cleaned
- Each test independent
- No shared state

**Validation:**
- JSON parsing and structure checks
- YAML format validation
- Error message verification
- Exit code validation

**Mocking:**
- Registry index generation
- Sample pack.yaml creation
- Checksum pre-calculation

## Technical Highlights

### Test Pattern: Isolated Execution

```rust
#[test]
fn test_pack_checksum_directory() {
    // Create isolated environment
    let pack_dir = create_test_pack("checksum-test", "1.0.0", &[]);
    
    // Execute command
    let mut cmd = Command::cargo_bin("attune").unwrap();
    cmd.arg("pack")
        .arg("checksum")
        .arg(pack_dir.path().to_str().unwrap());
    
    // Verify results
    cmd.assert()
        .success()
        .stdout(predicate::str::contains("sha256:"));
    
    // Auto-cleanup on drop
}
```

### Test Pattern: JSON Validation

```rust
let output = cmd.assert().success();
let stdout = String::from_utf8(output.get_output().stdout.clone()).unwrap();

// Parse and validate
let json: Value = serde_json::from_str(&stdout).unwrap();
assert_eq!(json["ref"], "expected-name");
assert_eq!(json["version"], "1.0.0");
assert!(json["install_sources"].is_array());
assert!(json["checksum"].as_str().unwrap().starts_with("sha256:"));
```

### Test Pattern: Error Handling

```rust
cmd.assert()
    .failure()
    .stderr(predicate::str::contains("pack.yaml not found"));
```

### Output Format Strategy

**Before (Contaminated):**
```
ℹ Calculating checksum...
{
  "checksum": "sha256:abc123"
}
✓ Done!
```

**After (Clean):**
```json
{
  "checksum": "sha256:abc123"
}
```

**Impact:** Cannot run API integration tests  
**Workaround:** CLI tests prove functionality  
**Resolution:** Separate webhook refactoring task

### 2. Network Tests
**Missing:** Git clone and HTTP download tests  
**Reason:** Require network or complex mocking  
**Future:** Add VCR-style mocking or local git server
